GARBIAGE STOP MECHANISM FOR TYPE-WRITING MACHINES.

Specificationof Letters Patent.

Patented Dec. 31, 1907.

Original application filed November 12. 1904. Serial N 0. 232. 113.Divided and this application filed May 18. 1905. Serial No. 260.985.

My invention relates to typewriting ma chines and has for. its object toimprove the carriage stop mechanism thereof.

' The invention will be fully described hereinafter and the features ofnovelty pointed out in the appended claims.

filed by me in the United States Patent Office November 12, 1904, SerialNo; 232,413.

' Referring now to the accompanying draw in'gs, Figure 1 is a sectionalelevation of a machine in which my improvements have been embodied; Fig.2-is a rear elevation thereof with parts in section; Fig. 3 is a detailsectional elevation of a column stopand Fig. 4 is a detail sectionalelevationof a margm stop. v V

In the drawings, -,1- represents the keys which are mounted on levers 2,fulcrumed on the frame of the machine at preferably in such a manner astobe easily removable. The levers 2 have any suitableconnection with anyapproved type mechanism (not shown) as-for instance through the mediumof an elbow lever iulcrumed at 5. key lever 2 also operatesthe'escapement mechanism in., any approved -manner "for instance,through the medium of a universal bar 6 engaged by a toe 2 on the keybar. A key lever 7 (Fig. 1) is connected by a link 8, with a rearwardlyextending lever 9,-fulcrumed at 10, the rear end of which engages callymovable stepped stop '12 arranged to be projected more or less intothepath of the carriage by suitable mechanism, or an ordinary stop(without steps) may beused when; denominational tabulation is notdesired. The stop 12 is adapted for engagement with.

the stop member 13' of a column stop 13 (or severaloi them) mounted onthe-rear rod 14 which is on the rear hinged'portion 1 5' of thecarriage.The stop member 13' may be pivoted to the casing13 and held by a spring1-3 either in the operative lower position shown in Fig. 1, or in anupper position in The present application is a division of one The whichit is out of action. The column stop has a handle 16 for adjusting itlengthwise of the rod, and a toe 17 for holding it after adjustment,said toe engaging a rack 18 on the rear portion of the carriage. Aspring 19 (Fig. 4) throws a ball 20 toward a top plate 21 having a ledgeor rib 21 so that the casing of thecolumn stop is thrown either towardthe rack 18 or away from it.

The margin stops 22 may be of. almost the same construction on thecolumn stop, except that the margin stop proper 23'has a limitedswinging v movement lengthwise of the rack 18 in the usual'manner.adjustable on the rod 14 (Whether column stops or margin stops) arepreferably r0- vided with two pointers 24, 25, adapts to indicate on thescale 26, one of such pointers being in operative osition whether thestop therefrom.

The release of the carriage from the escapement'for tabulating purposesis effected by means of an arm 27 mounted on the fulcrum 10 of the lever9. and turning with said lever. Thesaid ,arm carriesa roller 28(preferably on ballbea'rings) adapted to engage a smooth surface 29 v ofthe escapement rack or feed rack 30 (Figs. land 2). An adjustable stopscrew-31, ermits of regulating the normal position or the'roller 28.Thus atthe depression of the tabulating key, the roller '28 will, engagethe rack 30 and release the carriagefby swinging itsxentire rear ortion15 :away from the feed pinion 32 of t e escapebrought into the'path ofthestop 12. Furthermore the rack30 willbe brought against a stationarybrake strip 33. I ."I't-is to be understoodthat the carriage consists oftwo portions, the frontrportion 3e 'of'whichcarries the platen'35, andthe rear gortion .15 of whichcarries the rack- 30. o'th carriageportions are ivotally suported onthe-rear rodn36 .o the machine ame, onwhich rod the carriage ,travls transverselyof the machine.

Various modifications may be made without departing from the nature ofmy invention. 1 I I claim and desire to secure by Letters. Patent:

1. Ina typewriter-or like machine, a carriage having a swinging section,a feed memher and a column stop. carried by said swing The stops I isengaged with ,t e rack 18, or released -ment. 1 Atthe same timethe stop13'will be ing section and tabulating mechanism comprising a tabulatinstop adapted to co-' operate with said; co umn stop, an arm connectedwith said tabulating stop and provided with a roller journaled about asubstantially vertical axis and ada ted to en gage the feed member torelease t e carriage.

, 2. In a typewriter or like machine, a carria e rovided with a rod anda scale paralle t erewith, a sto adjustable lengthwise of said rodand caa le of a swingin rnove ment thereon, sai stop being rovi ed with twoointers facing toward eac other, either of which is adapted to indicateon said. scale according to theposition of the stop.

3. In a typewriter or like machineya carriage having a swinging section,a column stop carried by said swinging section, a feed member and abrake on the frame of the machine, a second feed member carried by theswinging section of the carriage and adapted to normally engage saidfirst named escapement member, said second'named escapement member beinglocated between the brake and the first named esca ement memher andmeans for swinging sai carriage section to disengage the escapementmembers and to swing said second named escapement member against thebrake.

riage comprising two sections, each movable relatively to the other, afeed member and a sto located on one of said carriage sections anmovable therewith, a second stop on the frame of the machine ada ted. tobe moved into 0 erative position an mechanism sep' arate om second namedstop yet connected therewith formovin'g the section of the carriage onwhich the stop is located, thereby movin said stop and releasing thecarriage from t e feedjmechanismn 5. In a t ewriter or like machineacarriage provi ed with a rod and a rack parallel 4. In a typewriter orlike machine, a car- H with the direction of its motion, and a barhaving a rib, and a stop adjustable lengthwise of said rod and arrangedto enga c said rack,-said stop having a spring presse member adapted toengage said rib on one side or the other. s

6. In a typewriter or like machine a carriage provided with a rod and ascale parallel therewith, a stop adjustable lengthwise of I said rod,andca able of a swingln movement thereon, said stoplbeing provi ed withtwo pointers one or t e other of which is ada ted to indicate on saidscale according to t eposition of the sto 4 7. In'at riage comprising aswingingrear section, a stop carried ,therebyso as to be movabletransversely of-the carriage path, a second stop located on the frame bfthe machine so as to be also movable transversely of the carriage pathinto operative relation with the ,first named stop, and means connectedwith the secondnamed stop bntseparate therefrom, for moving the carriagesection and with .it the first named stop, before the ypewriter or hismachine, a car second named stop engages any portion of JOHN Lorna,
